The Communications subsystem’s main responsibility is the development of telecommunication systems, which will allow us to monitor flight data in real time, as well as to remotely control the solar-powered UAV Phoenix.
4G-LTE and LoRa Communication
In the context of the Phoenix mission, which will cover the Seih Sou forest area, there is a need for a communication system with two way link coverage. Thus, the Communications subsystem carries out research on the design of an antenna that will allow the aircraft to communicate via 4G-LTE network with our Ground Control Station. Using electromagnetic analysis programs, we can confirm the design options of the antenna, and move on to its construction. The existence of the antenna will allow us both to monitor important flight data in real time, and to remotely check the otherwise autonomous aircraft in certain flight phases, such as landing.
For the next UAVs to be designed , we intend to implement a telemetry system, which will transmit flight data live, enabling us to obtain a more direct feedback on the performance of the aircraft. The system will utilise the LoRa communication protocol, which provides sufficient range for our test flights. In addition to the transmission system, which will be implemented in cooperation with the Hardware Development subsystem, a Ground Station will be designed, where we will receive the data and display it in a graphic interface.
